Identical mounting hole layout, shaft spline size, oil port position and gear displacement as the original 600057815 charge pump. Plug-and-play installation without mechanical modification, fully compatible with original Sauer Danfoss hydraulic transmission assemblies.

Adopts precision ground alloy steel gears and high-toughness shaft sleeves, effectively reduce internal leakage; stable flow output, low vibration and low noise under long-hour heavy-load continuous operation.

Integral cast iron pump body with multi-layer anti-wear oil seals and built-in charge relief valve. Wide operating temperature range, dustproof, mud-resistant and anti-electromagnetic interference, suitable for harsh farmland and construction site environments.

Each unit undergoes strict pressure calibration before delivery, keeps consistent make-up pressure within the rated range to eliminate system pressure fluctuation, stall and main pump burnout failures.
